 If the DataGuard server is open in the read-only mode it must be licensed. I believe the inactive stand-by does not need licensing unless active for more than 10 days a year. Ron

Oracle sales told me we need to license the DataGuard servers just like prod servers. I think the reasoning is there are active transactions occuring, but I'm not sure about this.

Subject: a really non-technical question, help?  

sorry, folks, but I though as many production DBAs as are on this list, I might be able to get an answer to this question. What I need to know is how Oracle licensing works on a hot-standby (e.g., a VCS failover node).

In this case I'm thinking that the failover node will never be running oracle *unless* the primary is dead. Seems like a single system worht of CPUs to license in my mind...any feedback ?
